WEFT-REPLENISHING LOOIVI'.

SPECIFICATION forming part of Letters Patent No. 774,459, dated November8, 1904.

Application filed November 17, 1903. Serial No. 181,520. (No model.)

To all whom, it may concern.-

Be it known that I, EARL A. THIssELL, a citizen of the United States,residing in Lowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented a certain new and useful Improvement inWeft-Replenishing Looms, of which the following is a specification.

This invention relates to weft-replenishing looms in which the fillingis renewed by substituting a full shuttle for an empty one, andcomprises means whereby the binder is moved outward from the shuttle-boxduring the expulsion of the empty shuttle and the introduction of a fullshuttle, thus preventing the stop movement of the dagger-rod orprotector-rod and the friction of said binder on said shuttles.Heretofore the binder has been provided with a projection arranged andadapted to be struck by a shuttle which is being transferred from the.magazine to the shuttle-box to crowd the binder out of the path of saidshuttle; but this projection has been found to wear the shuttle rapidlyand to roughen its surface in such a manner as to cause the threads tobe caught thereby and to be broken. Such a projection on the binder isshown in United States Patent No. 733,884, granted July 14, 1903, to me.I dispense with this projection and provide means operated by thetransferring movement of the shuttle-changer to move the binder out ofthe path of a shuttle being transferred.

In the accompanying drawings, on two sheets, Figure 1 is an inner endelevation of the shuttle-transferring mechanism, the lower part of themagazine, the shuttle-binder, dagger-rod finger, and other parts, and avertical section of lay-beam and dagger-rod; Fig. 2, a front elevationof the part shown in Fig. 1; Fig. 3. an inner end elevation of theshuttlechanger, its cam, and alever operated thereby on the line 3 3 inFig. 2; Fig. 4, an inner end elevation of thelower part of the magazine,the shuttle-box and shuttle-changer provided with a cam, the binder andanother form of the means which connect the binder and said cam; Fig.5,21 front elevation of apart of thelay with the shuttle-changer,shuttle-box, and the protector-rod or dagger-rod; Fig. 6, an outer sideelevation of a part of the sh Little-changing end of the loom, showingthe shuttle-box, picker-stick, protector-rod or dagger-rod, with itsfinger and dagger, the knock-off lever, and in vertical section thebreast-beam; Fig. 7, a plan of parts of the breast-beam, the notched andslotted plate, the protector-rod or dagger-rod and dagger, and in dottedlines the knock-off lever and in the horizontal section thebelt-shipper.

The lay-beam 6,the picker-stick E, the binder J, the dagger-rod orprotector-rod U, and the dagger-rod finger u are all of usualconstruction as used in looms for weaving plain cloth and ginghams. Theprotector-rod U is a rockshaft, supported on the lay-beam, and thefinger u is rigidly secured to said rod and is normally pressed againstthe binderJ near the free end of said binder to crowd the binder towardthe back of the shuttle-box by a spiral spring a, Fig. 5, which resiststhe rocking of the protector-rod. The protector-rod also carries adagger 10 which projects forward and passes under the breastbeam a whenthe lay swings forward. l/Vhen a shuttle is in either shuttle-box duringthe forward swing of the lay, the free or front end of the dagger-rod isdepressed sufiiciently to pass under the knockoff lever V, pivoted at eon the under side of the breast-beam a; but when during such forwardmovement there is no shuttle in either shuttle-box the dagger strikesthe long arm of said knock-off lever and causes the short arm of saidlever to press the belt-shipper W out of the notch 00 in the slotted andgrooved plate X, whereupon said belt-shipperis caused by a spring (notshown) to swing outward in the slotw of said plate X and to shift thebelt from the fast to the loose pulley in a wellknown manner. Obviouslyany contrivance which prevents the binder from swinging into theshuttle-box will prevent the above-described operation of theprotector-rod. Vith these parts may be used any suitable magazine,movable shuttle transferring device, adapted to receive shuttles one ata time from said magazine and to place them on the lay. beam, and meansoperated by the movement of said transferring device to move the binderaway from the shuttle-race and allow a shuttle to be placed on saidrace.

I have shown a magazine F, rotary shuttlechanger M, pawl-lever P turningon the shaft 1, on which said changer M rotates, and connected by a rodor link Q to a lever, (not shown.) as fully shown and described in saidpatent and in another patent, No. 73 L007, granted July 21, 1903. Theconstruction of these parts is' not of the essence of my presentinvention, and it is sufiicient to say that upon the breaking orexhaustion of the filling or weft the changer M is caused to make apartial revolution upon the shaft I and to carry a shuttle which isbeneath the magazine in the upper compartment of said changer or incontact with the wing of of said changer which, for the time being, isuppermost to the shuttlerace between the binder and the shaft 1, whilethe wing m which, at the beginning of said partial revolution forms thetop of the shuttle-box, passes down behind the binder and pushes thenext previously operative shuttle through an opening in the bottom ofthe shuttle-race. When the last-named wing passes below the binder,thebinder,unless prevented,

will swing into the shuttle-box and allow the 5 dagger-rod to operate tostop the loom, be-

below the top of the binder. Even if the loom To prevent these occurorshuttle-compart- 3 movement of the dagger-rod or protector-rod. Each cam-surface in turn holds the binder away from the path of the shuttleuntil the shuttle-changer has completed its partial rotation, and saidcam-surface terminates suddenly in a radial plane d, which allows thelower arm of the lever C to be moved suddenly in toward the center ofthe cam, which it will be caused to do by the usual daggerrod spring12/.

In Fig. 4 I have shown a single two-armed lever C fulcrumed on a bracket(1 secured on the lay above the back of the shuttle-box port orentrance, one arm 0 of said lever reaching across the shuttle-box andbearing against the inner face of the free end of the binder and theother arm (J of said lever being held by a spring, represented as aspiral spring 0 against a cam D, which is not essentially unlike the camD, and rotates with the shuttle-changer. Obviously the rotation of thecam D will operate to swing the binder away from the shuttle, as abovedescribed in the case of the cam D. In Fig. i the cam D and both arms ofthe lever C are represented as being between the magazine and the middle of the lay and do not, therefore, lie in the path of the shuttlebeing transferred, while i the arm 0 of said lever does not when inincause the new or full shuttle has not yet passed 1 Inents, eachcam-surface acting upon such lecrank levers G C, fulcrumed upon stands 0a,

secured upon the lay-beam band magazine F, respectively. The lever C hasan arm a, which bears against the inner face of the binder J near thefree end of the same, and another arm a, which extends over theshuttle-race and under the arm of the lever C, the lower end 0 of theother arm a of said last-named lever being suitably rounded to rideeasily over the steps (I of the cam D. The cam D rotates with theshuttle-changer and acts upon the lever U just as soon as said changerbegins to turn, pushing the binder away from the shuttle in the box toallow said shuttle to leave the box without friction on said binder andpreventing the binder from getting in the path or rubbing on the sideand lower corner of the entering shuttle and at the same time preventingthe stop-motion operative position project in advance. of the back ofthe shuttle-box and. does not, there-- were not stopped the binder wouldbe in the path of the new shuttle and prevent its reach- 5 fore,interfere with the traversing movement of the shuttle. In both cases thecam D D permits the shuttle-binder to swing into the shuttle-box whenthe shuttle-changer is not rotating.

I claim as my invention 1. The combination of a shuttle-changer, abinder and means independent of the shuttle operated by the transferringmovement of said shuttle-changer to move said binder out of the path ofa shuttle being transferred.

2. The combination of a shuttle-changer, binder, a protector-rod,controlled by said binder, and means independent of the shuttle operatedby the transferring movement of said shuttle-changer, to move saidbinder out of the path of the shuttle being transferred and to preventthe operation of said protector-rod.

3. The combination of a shuttle-changer, a cam movable therewlth. abinder and means connecting said cam and said binder, to move saidbinder out of the path of a shuttle being transferred.

a. The combination of a lay, a rotary shuttle-changer, a cam, rotarywith said shuttlechanger, a binder, and a lever carried by said lay andoperated by said cam, to move said binder out of the path of a shuttlebeing transferred.

5. The combination of a lay, a rotary shuttle-changer, a cam, rotarywith said shuttlechanger, a binder, a lever carried by said lay saidbinder out of contact With the shuttle and operated by said cam,tomovesaid binder being transferred.
